Versuchsvorschrift

Into 800 g of blocks of ice, a solution of 36.9 g of cyanuric chloride in 320 ml of acetone was added dropwise with stirring to prepare a dispersion. 18.6 g of aniline was added dropwise at temperature of 5° C. or lower into the dispersion. At the same time of the addition of aniline, 210 mL of 5% sodium carbonate aqueous solution was added dropwise at temperature of 5° C. or lower with keeping the same dropping rate as in the addition of aniline to the dispersion, to precipitate crystal, whereby 2,4-dichloro-6-phenylamino-1,3,5-triazine was obtained.
